AN364: Rapid Determination of Total Fat from Dairy Products

Instrument Type: Automated Sample Prep

The U.S. Nutritional Labeling and Education Act of 1990 requires nutritional labels listing the content of saturated and unsaturated fats in food. Accurate determination of fat in certain foods is difficult due to the binding or entrapment of the fat by the matrix. Accelerated Solvent Extraction (ASE) is an automated extraction technique that significantly reduces extraction time and solvent consumption and yields equivalent results. In this work, fat was extracted from sour cream, cream cheese, coffee creamer, heavy whipping cream, and low-fat milk.

AN329: Determination of Total Fat in Powdered Infant Formula Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

The U.S. Nutritional Labeling and Education Act of 1990 requires that food products carry labels listing the content of saturated and unsaturated fats. Accurate determination of fat in certain foods is difficult due to the binding or entrapment of the fat by the matrix. Accelerated Solvent Extraction (ASE) is a new automated extraction technique that can significantly reduce extraction time and solvent consumption and yields equivalent results, without requiring a pretreatment step. In this application note, fat is extracted from infant formulas by ASE without aggressive pretreatments.
